The use of copper tailings as supplementary cementitious material can reduce the environmental impacts ofconcrete production and the mining industry. A key concern limiting its application is the potential leaching oftoxic ...

This thesis aimed to develop self-healing ECCs with PVA, polypropylene and recycled polyester fibers. As healing agents, silica fume, crystallizing additive and bacterial solution were used. For autonomous agents, three ...

The use of supplementary cementitious materials (SCMs; e.g., slag, fly ash) to reduce the amount of ordinary Portland cement in concrete construction has increased significantly over the last 20 years. Previous research ...

The use of tailings as aggregate and supplementary cementitious materials has been studied previously. Nevertheless, tailings are generally used as collected, without treatment, showing low cementitious capacity allowing ...

Three mixtures were made for conventional concrete with different additions of cement, 300 kg/m3, 350 kg/m3 and 400 kg/m3, being these the 3 designs of mixtures more used for the elaboration of simple concretes. For each ...
